Title: Zinc salts of aminothiophenols and their use as plasticizers for elastomeric compositions
IPC: C07C323/41
Filed: 1954-09-22
Abstract: Synthetic rubbers are plasticized with zinc salts of aminothiophenols (see Group IV (b)) of the formula:- <FORM:0761824/IV(a)/1> where R is an alkyl or alkoxy radical of 1-4 carbon atoms, a phenylamino radical, an aryl radical of 6-12 carbon atoms or a heterocyclic radical.  Synthetic rubbers specified are copolymers of butadiene-1 : 3 and styrene or acrylonitrile.  In an example, a butadienestyrene (80 : 20) copolymer is milled at 100 DEG  C. for 10 minutes with zinc o-carboisobutoxyamidothiophenate and the viscosity compared with an untreated sample and a sample treated with dibenzamidodiphenyldisulphide.ALSO:The invention comprises zinc salts of aminothiophenols of formula <FORM:0761824/IV(b)/1> where R is an alkyl or alkoxy radical of 1-4 carbon atoms, a phenylamino radical, an aryl radical of 6-12 carbon atoms such as phenyl, tolyl, xylyl or naphthyl, or a heterocyclic radical such as furyl, thienyl, pyrrolidyl or pyridyl.  The compounds are used as plasticizers for natural and synthetic rubbers (see Groups IV (a) and V) and are prepared by reacting the corresponding o,o1-disulphide with zinc dust and hydrochloric acid.  The reaction is preferably carried out in an inert alcohol solvent such as methanol, ethanol or butanol.  In examples: (1) o,o1-dibenzamidodiphenyldisulphide and zinc dust are slurried in methanol, hydrochloric acid is added and after refluxing for 1 1/2 hours the mixture is filtered and the filtrate is poured into water to precipitate zinc o-benzamidothiophenate; (2)-(6) using procedures similar to (1) and starting with the corresponding o,o1-disulphide the following are prepared: zinc o-phenylcarbamido-, o-acetamido -, o - (2 - furoylamido) -, o - carboethoxyamido - and o - carboisobutoxyamido - thiophenates.ALSO:Rubber is plasticized with a salt of an aminothiophenol (see Group IV(b)) of the formula: <FORM:0761824/V/1> where R is an alkyl or alkoxy radical of 1-4 carbon atoms, a phenylamino radical, an aryl radical of 6-12 carbon atoms or a heterocyclic radical.  Generally between 0,01 and 5 per cent of the zinc salt is used.  In Examples samples of rubber are milled for 10 minutes at 212 DEG F. with the following zinc salts: zinc o-benzamido-o-carboethoxyamido-, o-acetamido-, o-(2-furoylamido)- and o-carboisobutoxyamido-thiophenates and the viscosities are compared with an untreated sample and one treated with dibenzamidodiphenyldisulphide.

Systems, electric; contacts, arrangement of; external spark gaps; timing.-A transformer c', c<2> is provided for each two engine-cylinders, with a single battery e, condenser n and contactbreaker m, the secondary winding of each transformer being connected at each end to a sparking plug. A cylindrical casing may be used for a set of transformers and the associated condenser, spark gaps being arranged externally of the casing and across the terminals of the secondary winding for giving an indication of any defect in the plug circuits. The transformer casing is mounted on brackets immediately over the engine cylinder block, permitting the use of very short leads to the plugs. The cam m, Fig. 6, breaks the primary circuits in turn by separating the contacts carried by the arms k<1>, k<2> from the fixed contacts k<o>. The cam is driven at engine speed, .and is adjusted automatically by the centrifugal action of a coupling which comprises masses r connected to the driven shaft by metal strips r<1>, r<2> lodged within slots in a plate q<2> on the driving shaft. A helical spring opposes the action of the members r. Excessive current through the primary windings is prevented by the insertion in the circuit ef a resistance g, preferably of steel wire, suspended from pillars g<1>; a low-voltage lamp v is shunted across part of this resistance.

Classes 125(ii) and 125(iii) A bottle, can, or like container 6 is sealed by placing thereon a metallic closure blank the skirt 2 of which has an annular bulge or shoulder at at 4, in which is positioned a liner 5 larger in size than the sealing surface of the container, Fig. 1, applying pressure to the blank (as by causing relative movement between the container and a pressure block 7 comprising a knock-out plunger 8) to force the margin of the liner into engagement with the side sealing surface and superimposing a portion of the skirt on the margin of the liner, Fig. 2. In a modification, Figs. 7, and 8, pressure applied to the top 31 and bulge 34 of a blank causes the shoulder 37 to bear against the margin 38 of a liner 35 and to force the margin around the container finish and a portion 39 of the skirt, of smaller diameter than the shoulder, slips over the margin further pressing the liner against the side of the container and drawing the flat portion of the skirt into intimate contact with the top of the container. The closure may be secured by subsequently re-forming the skirt to a threaded configuration, as by application of a revolving roller 9 or by the lug and bead arrangement of a snapon type closure, Figs. 9-11 (not shown), the lugs being preformed or formed simultaneously with the pressing by a member (not shown) co-operating with the block 7.

[Also in Division H1]  Prior to the sealing of an electric lamp bulb on to the bulb foot, the interior of the flange of the latter is marked to facilitate later fitting of the cap in the proper position relative to the electrodes. An applicator 4 consists of a pair of rubber fingers 22 carried between clamping plates 21 on the end of a shaft 5. This shaft is mounted at its other end in a U-bracket 6 carried by a rotatable sleeve 7 adapted to be rocked between horizontal and vertical positions (Figs. 3 and 1 respectively). Shaft 5 can be rotated about its own axis by bevel gearing 11 to rotate the applicator.
